AN'IISLIP ATTACHMENT FOR FOOTWEAR.

Application filed Karch 29, 1926. Serial No. 98,294.

'.-I presentinvention relates to improve- .lilltS in anti-slippingattachments for foot- Y which will be extremely light in weight, and

one wherein, the ground engaging portions thereof are so arranged as toprevent rearward slip ing of the \vearers foot while walking.

Other objects and advantages of the invention will beapparent during thecourse of'the following detailed description, taken in connection withthe accompanying drawing forming a part of this specification, and inwhich drawing,

Figure 1 is a diagrammatic top plan view of a shoe and showing thedevice applied thereto.

Figure 2 is a side elevation of a shoe and showing the device appliedthereto.

Figure 3 is an enlarged fragmentary top plan view of the rear portion ofthe device.

Figure 4 is an enlarged fragmentary section on line 44 of Figure 3 andlooking in the direction of the arrows.

Referring to the drawing in detail, and \vherein similar referencecharacters designate corresponding parts throughout the several Views,the letter A may designate a boot or shoe, en'ibodying a sole portion Band an instep C. The letter D designates the tread or ground engagingportion of the device, and Ev means for detachably securing the treadportion D to the sole nortion of the shoe A. Y

Referring to the tread portion or member D, and which is preferablystamped from sheet metal, the same embodies a sole portion 10 conformingto the configuration of the sole of a boot or shoe, and a rear or instepportion 11.- The sole portion 10 is formed at its marginal edge with anupturned flange 12 which engages each edge of the sole B and extendsaround the toe portion of the sole as clearly illustrated in Figure 2.The-instep portion 11 is formed flat, the flange 12 at each side of thesole portion 10 merging into the instep portion at the juncture of the;sole and instep portions. Ex-

tending around the marginal edges of the tread member D, is ametalbinding13 which may be of U-shape in cross section, and which bindingserves for covering the roughened edges of the tread member. This metalbinding may be secured to the tread member in any suitable manner suchas crimping or welding. This metal binding is desirable, since it ispreferred that the .tr'ead member be stamped and then cut to the desiredshape.

Referring to the specific formation of th sole and instep portions 10and 11 respectively, the same consists of so forming the portion as toprovide a plurality of transversely extending tread sections 14 arrangedin staggered relation transversely of the tread member, and which treadsections are connected at their ends by diagonally extending websections 15. As will be observed in Figures 3 and 4, these treadsections 14 are inclined pwardly and forward- 1y of the tread member,and that the diagonally extending web sections 15 extend rearwardly fromthe lower portion of one treadsection, upwardly to "the upper portion ofits companion rear tread section. Thus it will be seen that the treadsections 14 which extend transversely of the tread member, are inclinedupwardly and forwardly, while the diagonally extending web sections 15extend in an upward and rearward direction thus providing a seriesofground engaging transversely extending edges 17 arranged in staggeredrelation transversely of the treadmember. It will also be observed thatby so inclining the tread sections ltforwardly and u )wardly, that whenwalking, ones foot will be prevented from slippmg rearwardly since thebackward pressure of the foot Will cause the edges 17 to diginto the iceor snow for affording sufficient traction-to the wearer of the device.

Secured to each side and at the rear side of the instep portion 11, arebails 18, while the forward portion of the sole portion 10 has securedto the upper edge of the flange 12 transversely aligned bails 19, andwhich bails 18 and 19 preferably extend upwardly in substantially rightangular relation with the major plane of the tread member.

Anchored at its opposite ends in the bails 18, isan ankle strap 20provided with a buckle 21 for attachment of the strap for drawing theinstep of the shoe.

In use, it will be seen that the flange 12 will engage the marginaledges of the sole l3, and that by so having the instep portion ll flat,when the strap 20 is drawn u tightly, the instep portion. It will yielat its juncture with the sole portion 10, thus a1- lowing the instepportion 11 to be drawn into tight engagement with the instep C and allowfor a suflicient amount of flexibility between the sole B and instep C.

From the foregoing description it will be apparent that a novelanti-slip attachment for footwear has been provided, embodying featuresfor affording sufficient traction to the wearer when traveling uponslippery or ice covered surfaces, and which device is of suchconstruction as to allow for proper flexing of the sole of the footwearto which the device is attached.

Changes in detail may be made to the specific form of the inventionherein shown and described, without departing from the spirit of theinvention or the scope of the following claims.

I claim:

1. A device of the class described eomprising a tread member formed withelongated tread sections extending in offset parallel relation to oneanother transversely of the member and connected by diagonally extendingweb sections, and means for attaching the member to the sole of anarticle of footwear.

2. A device of the class described comprising'a tread member havingupwardly turned flanges at its i'orward portion and formed with aplurality of transversely extending forwardly inclined tread sectionsconnected at their ends by diagonally extending web sections, and meansfor securing the member to the sole of an article of footwear with saidflanges en'ibracing the l'narginal edges of the sole.

3. Tn a device of the class described, a tread member formed with aplurality of transversely extending forwardly inclined tread sectionsconnected at their ends by rearwardly inclined diagonally extending websections.

4. In a device of the class described, a tread member embodying aplurality of transversely extending tread sections disposed in forwardlyand upwardly inclined relations, and diagonally extending websconnecting said tread sections and extending from the lower portion ofthe tread sections rearwardly and upwardly to the upper portion of therespective rear tread sections.
